SPECIFICATION forming part of Letters Patent No. 520,818, dated June 5, 1894.

Application filedlanuary lti, 1894.

I To all toho m it may concern.-

Be it known that I, JOHN J. BETTINGEE, of

. Hamilton,Butler county, Ohio, have invented certain new and useful Improvements in Wire- Strippers, of whichthe following is a specification.

from the following description, taken inconnection with the accompanying drawing, which is a perspective View of my improved wire stripper.

Referring to the drawing:-A and B indicate a pair of metallic handles of sufficient length to be firmly grasped in the hand; 0, a spring bow uniting one end of the handles and tending to hold them a normal distance apart and permitting them to be squeezed closer together; D, a blade projecting inwardly at right angles from the end of handle B; E, a similar blade projecting inwardly from handle A, the ends of these blades'standing normally apart from each other and being oapable of over-lapping in contact when the two handles are pressed toward each other; F, a

triangular notch in the end of blade D, this Serial No. 497,091- (No model.)

notch having straight walls which are brought to a knife edge and hardened; G, a similar notch in the end of blade E.

To use the implement the wire is inserted between the open blades which are then forcibly compressed upon the wire and given a twisting motion which causes the sharp straight sides of the notches to cut shear-like through the insulation down to the wire. The

implement is then, while still firmly squeezed upon the wire. given an endwise pull, thus stripping the fibrous covering from the wire. 0

knife edges.
